hybrid organic–inorganic perovskitesSubstitution of A‐site and/or X‐site ions of ABX3‐type perovskites with organic groups can give rise to hybrid perovskites, many of which display intriguing properties beyond their parent compounds. However, this method cannot be extended effectively to hybrid ...
Replacing the Aand/or X﹕ite metal ions of the perovskite architecture with organic amine cations and/or molecular bitopic linkers leads to a subヽlass of perovskite materials, namely hybrid organic–inorganic perovskites (HOIPs). Importantly, the incorporation of organic components in the HOIP ...
